attributeHiddenField -- what is its purpose ?

Hello,

When products in a shopping cart are displayed there is a attributeHiddenField that is made use of.

What exactly is the purpose of this field?
Where is the contents of this field set or configured?

appreciating your response,

Daniel

ps. its only used in all of zencart (admin/catalogue):

includes/modules/pages/shopping_cart/header_php.php
includes/templates/<customTempate>/templates/tpl_shopping_cart_default.php
includes/templates/template_default/templates/tpl_shopping_cart_default.php

Hmm
Are you talking about zen_draw_hidden_field?

Hello,

Thank you for the reply. Yes, amongst others also this ...

Here are several relevant lines obtained from the toolkit ...

I am contemplating whether i can use that field to somehow add custom information i'd like to maintain for products in the shopping cart and products in orders.
